'Loads-rs, of w rich the following isa speciica'tion.

My present invention pertains to improved dirt and manure loaders,` the construction and advantages of which will be hereinafter set forth, reference being had to the annexed drawings, wherein: i

Figure 1 is a sectional elevation 0f the paratus; Fig. 2 a top plan thereof; Fig. 3 a horizontal sectional view, taken on the line 3 3 of Fig@r l, the parts being somewhat enlarged g and Fig. 4' a transverse vertical sectional View, taken on the line 4-4 of Fig. 2, the parts being somewhat enlarged in thisliigure.

The object of my invention is to provide a simple apparatus in which the dirt or-other material may be loaded upon a platform, which platform being loaded occupies a position substantially even with the ground, so

., that it may be loaded by scoops or shovels.

Combined with the platform is means for raising the same, dumping the platform when raised, and means for lowering the platform after the load has been removed therefrom.

Referring to theilrawin'gs, the base or sun port for. the apparatus comprises a' longitudinally-disposed timber or girder A, provided at its forward end with a cross or foot piece B and at the rear end with a similar piece()Y A derrick or sheer D is mounted upon the forward end of the girder, and a hoistingcable E, connected at its front end to a crossbar F, passes over a puller G, mounted in a bracket H, secured to the upper portion of the derriclr or sheer, the cable passing under a second ulley l mounted upon a bracket J, securedp to the lower end of the inner or rear member of the sheer and to the girder A. Thecable then passesrearwardly to a drum or winch K, which is supported by the member C.

The cross-bar F issecured between side bars or arms L, said members 'forming a frame which is pivoted to the bracket d',

or upon an axle lvl carried by said bracket The frame has pivctally secured to its vcuter end a platform or table N, the fulcruni there-- of being in rear of its center, so that the table has a tendency to tilt or tip forwardly.

A cable O is secured to th'e under face of the table at the innermost edge thereofand passes beneath a cross-bar F, and a out a drum'Q mounted upon a shaft R journaled in suitable brackets secured to the rear member of the derrick. The shaft is provided With a ratchet-Wheel S and a crank or handle T.

The retrograde movement of thedrum,4 which would permit the cable C) to unwind and the platform or'table to tilt, is prevented by a gravitating dog U, which drops into the teeth of the ratchet-wheel S.

A sweep "V' is secured tothe windlass K, and by this means the windlass is rotated'so as to wind the cable E'around the same and cause the swinging frame to be drawn from the position shown in full lines to that shown in dotted lines in Fig. l. The windlass is likewise provided with a ratchet-wheel W (see Fig. 3), and a pawl X is normally held in contactwith, the teethl of said wheel by a spring Y.

A band-brake Z passes around the windlass, one end of the band being secured to a lined stud or member A which also forms the fulcrum of a lever B. The other end of the band is' attached at C. to the lever B', and a link D connects said lever with the pawl X An actuating rod E is secured to the outer end of the lever and extends for-A wardly to a link F which in turn is ivotall connected to a handle G, which andle 1s pivoted to the timber A at a point adjacent to or Within easy reach of the crank TrA gulley P, carried bythe ln operation, the material is scraped or drawn upon the platform or table While the thereunder, the o erator releases the drum Q and allows the p atform or table to tilt and discharge theload. After the material has passed ou the table, the cable C is again aling out the cable O f wound about the drum and the platform brought to its originel horizontal position. By then manipulating the handle G", the pawl .n is withdrawn trom the ratchet-wheel W and at the same time the band-brake Z is applied to the Windlass. This frees the Windlass and (permits the cable'E to unwind therefrom an the Swingin frame to drop to the position shown in in lines in Fig. 1. The descent of the rameand table may be regulated hy a plying more r less pressure upon the bandrake through the manipulation of the handle G.

`the retro rade movement of the handle the hand-bra eV will be released and the pawl thrown into operative relation with the ratchet-Wheel, so that when the cable E is again wound about the windlass it will' be held in that osition until the handle G is moved to wit draw the` awl.

. Having thus describedJ I claim is:

1. In an apparatus of the character specified, thevc'om ination of a base; a derrick mountedlu on one end thereof; a swinging frame, the orward end of-said frame extending outwardly from the baseand derrick; a platiormpivo'tally secured to the outer end' of the frame; means for normally holding said platform in its horizontal position; a

windlass; a cable passing from the windlass over the upper'portion of the derrick and connected to the swinging frame; a pawland-ratchet device serving to hold the Windlass against movement in one direction; a band-brake and means for withdrawing the pawl from the ratchet and simultaneously Immediately. uponA my invention, what Q teinte apparatus; means for actuating said drum maintaining it in its desire position; la cable passing from the drum beneath -the pulley and connected to the adjacent portion of the platform or table; a windlass; a paWl-` and-ratchet mechanism for holding said windlass-against motion in one direction; a band-brake passing about the windlassor a brake suriaceiormed thereon; means,l for simultaneously withdrawing the pawl from the ratchet and applying the band-brake; and a cable passing from vthe Windlass over the upper portion of the derrick and connected to the swinging frame.

In testimony w ereof I have signed my name to this specicationlin the presence of two subscribing witnesses.
